**                     unrestricted access to the repository.
**
**    main-branch      The primary branch for the project.  Default: trunk
**
**    manifest         If enabled, automatically create files "manifest" and
**     (versionable)   "manifest.uuid" in every checkout.  The SQLite and
**                     Fossil repositories both require this.  Default: off.
**
**    max-loadavg      Some CPU-intensive web pages (ex: /zip, /tarball, /blame)
**                     are disallowed if the system load average goes above this
**                     value.  "0.0" means no limit.  This only works on unix.
**                     Only local settings of this value make a difference since
**                     when running as a web-server, Fossil does not open the
**                     global configuration database.
**
**    max-upload       A limit on the size of uplink HTTP requests.  The
**                     default is 250000 bytes.
**
**    mtime-changes    Use file modification times (mtimes) to detect when
**                     files have been modified.  (Default "on".)
